## What is WBV?

Whole-body vibration refers to the vibration transmitted to the human body whilst supported by a vibrating surface. The most common exposure occurs through the buttocks when seated in a vehicle. Long term exposure to high amplitude whole-body vibration is strongly associated with the development of back pain and other adverse health effects.

The Whole Body Vibration application (WBV) utilizes the accelerometer within an iPod or iPhone to provide an estimate of vibration amplitude consistent with the methods described in ISO2631.1. Frequency weighted r.m.s and VDV values are presented graphically with reference to the health guidance caution zone for exposures of varying durations. Summary data and acceleration time series are available to be emailed or downloaded.

The application is intended for use within occupational contexts to provide a simple screening or monitoring tool for use by workplace safety and health staff. It is suitable for use to estimate whole-body vibration amplitude of seated operators of all vehicles, plant or equipment. Use is straight forward. After entering trial information, sampling is commenced with a tap and the device placed on the operator’s seat during a period of normal operation. At the completion of the period, sampling is ended with a tap and the results calculated and made available for viewing and emailing.

The application has been developed by the consultants at the Byte Works under direction of Robin Burgess-Limerick, Professor of Human Factors in the Minerals Industry Safety and Health Centre at The University of Queensland, AUSTRALIA. The project was funded by the NSW Coal Services Health and Safety Trust.

WBV supports the use of GPS, optionally in the foreground and always when background processing is used. The location information is included in the raw data file, which is available using the export features. Continued use of GPS running in the background (or foreground) can dramatically decrease battery life. You can turn GPS on or off using the WBV preferences, available from the Settings app.

### 3/5 — Is this open source app?

*2022-11-30*

Hi, it appears like this app is for researchers use. If that is the case, is the source code of the app available on GitHub?

## Frequently asked questions about WBV

### What is WBV used for?

WBV is used to estimate whole-body vibration amplitude transmitted to the human body. It helps assess potential health risks, such as back pain, associated with prolonged exposure, particularly for seated operators of machinery or vehicles.

### How does WBV work?

WBV utilizes the accelerometer within your iPhone or iPod to measure vibration amplitude. It presents this data graphically, referencing health guidance zones for different exposure durations, and provides summary data and acceleration time series.

### Can I share the data collected by WBV?

Yes, the summary data and acceleration time series collected by WBV can be emailed or downloaded. This feature is useful for workplace safety and health staff for monitoring and reporting purposes.

### Does WBV support GPS?

WBV supports the optional use of GPS, which can be enabled in the app's preferences. Location information is included in the exported raw data file, but continued GPS use in the background can significantly decrease battery life.

### What devices is WBV compatible with?

WBV is compatible with iPhone and iPod devices. It is suitable for use on the operator's seat during periods of normal operation to capture vibration data.

### Is WBV suitable for general users or only professionals?

While developed for occupational contexts, WBV is straightforward to use. It's intended for workplace safety and health staff to provide a simple screening or monitoring tool for seated operators.

### How often is WBV updated?

The latest version of WBV is 2.3.3, last updated on July 12, 2021. This indicates a moderate update frequency for the application.

### What is the age rating for WBV?

WBV has an age rating of 4+. This means it is considered suitable for users aged 4 and above, indicating no mature content.

## Version history (last 5 releases)

### 2.3.3 — 2021-07-12

Minor updates to keep up with iOS changes.

### 2.3.2 — 2016-11-14

This app has been updated by Apple to display the Apple Watch app icon.

• Corrected an incompatibility with iOS 9 and iOS 10 that prevented data collection in the background.

### 2.3.1 — 2015-12-22

1. The results.cv and exchange.wbv files that were previously only available as email attachments are now also saved with other application data. This means iTunes can be used to manually copy these files to a desktop computer.

2. Some minor formatting issues that cropped up under iOS 9 have been fixed.

### 2.3 — 2015-06-04

GPS data is now optionally supported for the raw data files. This allows offline processing to correlate vibrations with location.

Background processing is supported, so you can use other apps or allow the device to go to sleep while still collecting data. You also get data if the battery dies during collection, right up to the time where the device looses power.

Both GPS and background processing can be disabled in the preferences to extend battery life.

Sample time limits are supported to automatically break long samples into smaller, more easily analyzed chunks of data.

### 2.2 — 2014-06-29

1. Multithreading makes calculations nearly twice as fast on newer, dual-core machines. It's also quad-core ready!

2. Cancel buttons have been added so you can abort long calculations for large data sets when entering the detailed view or the 1/3 octave plots.

3. Fixed a bug that caused 1/3 octave plots to improperly display Y axis vibrations.
